Blair could face contempt of parliament

Davis said: “It’s a bit like contempt of court, essentially by deceit. If you look just at the debate alone, on five different grounds the house was misled – three in terms of the weapons of mass destruction, one in terms of the UN votes were going, and one in terms of the threat, the risks. He might have done one of those accidentally, but five?”

Salmond said he believed Corbyn’s support would mean the motion had enough cross-party support. “No parliament worth its salt tolerates being misled,” Scotland’s former first minister told ITV’s Peston on Sunday.

Asked about the potential vote, Corbyn told Marr he would probably back the motion. “Parliament must hold to account, including Tony Blair, those who took us into this particular war,” he said.
